Do I need D tires?
Would I gain much by using load range D tires on a 4500 lb GVWR dual axle trailer? My current load range C tires (Karrier Loadstar 205/75 R 14) have held up well. They have a 1760 lb load rating, w...

As I said before..... A tire with a higher ply rating has benefits beyond the load rating. It is more puncture resistant. I also said that this MAY be important to you.... Many of us DO tow off the pavement. Especially out west. For us it is the "norm" If that is not your "norm", by all means, ignore my advice....Heck, even if it is your norm, you are free to ignore my advice.... It is your money, and your time spent changing tires.... And ultimately, your choice.
Identical tires with a load range increase from “C” to “D” are still physically the same designated size. Without documentation of the addition of a durability factor they are both equal in that respect. The “D” has an increase in ply rating. The materials needed to allow the tire to become stronger and carry more weight via increased inflation pressures in no way (unless documented) increases that tires durability.
Some tire manufacturers will, at some point, add an extra steel belt for puncture resistance. That is strictly a durability item and it has no effect on the tires load capacity.
The example was in my last paragraph. What proof is there without a tire manufacturer's statement to the fact? A lot of their individual information is confidential and they are not going to reveal it for all to see.
Please remember that you mentioned "puncture resistant". That's a durability factor and a tire manufacturer would never miss the opportunity to tout better durability.
For instance; GY advertises the addition of scuff guard protection built-into their Endurance ST tires. They have nothing to do with the tire's strength. However, they are probably more resistant to curb strikes.
